“…This family consists of two subfamilies (Phyllanthoideae and Antidesmatoideae), 10 tribes, 57 genera, and 2050 species [5]. Certain taxonomic discrepancies exist within Phyllanthaceae, i.e., Phyllanthus is polyphyletic since species of genera Breynia, Glochidion, Sauropus, and Synostemon were found embedded in its phylogeny [3,6,7]. Moreover, taxonomic discrepancies exist at intra-genus level since several subgenera and sections of Phyllanthus were paraphyletic [6,8].…”

Family Phyllanthaceae belongs to the eudicot order Malpighiales, and its species are herbs, shrubs, and trees that are mostly distributed in tropical regions. Here, we elucidate the molecular evolution of the chloroplast genome in Phyllanthaceae and identify the polymorphic loci for phylogenetic inference. We de novo assembled the chloroplast genomes of three Phyllanthaceae species, i.e., Phyllanthus emblica, Flueggea virosa, and Leptopus cordifolius, and compared them with six other previously reported genomes. All species comprised two inverted repeat regions (size range 23,921–27,128 bp) that separated large single-copy (83,627–89,932 bp) and small single-copy (17,424–19,441 bp) regions. Chloroplast genomes contained 111–112 unique genes, including 77–78 protein-coding, 30 tRNAs, and 4 rRNAs. The deletion/pseudogenization of rps16 genes was found in only two species. High variability was seen in the number of oligonucleotide repeats, while guanine-cytosine contents, codon usage, amino acid frequency, simple sequence repeats, synonymous and non-synonymous substitutions, and transition and transversion substitutions were similar. The transition substitutions were higher in coding sequences than in non-coding sequences. Phylogenetic analysis revealed the polyphyletic nature of the genus Phyllanthus. The polymorphic protein-coding genes, including rpl22, ycf1, matK, ndhF, and rps15, were also determined, which may be helpful for reconstructing the high-resolution phylogenetic tree of the family Phyllanthaceae. Overall, the study provides insight into the chloroplast genome evolution in Phyllanthaceae.

“…The species is morphologically related to P. mocotensis G.L Webster and P. carvalhoi G.L Webster, but can be distinguished from the former because it is an herb with typically phyllanthoid branches (vs. subshrub, with rigid branches with fissures), and from the latter by having oblong leaves, rarely falcate (vs. falcateasymmetrical). From a phylogenetic point of view, until now, the studies carried out (Samuel et al 2005;Kathriarachchi et al 2006;Bouman et al 2020, Hidalgo et al 2020 have not included P. itatiaiensis. For this reason, one of us (J.C.R.…”

We report here the rediscovery of Phyllanthus itatiaiensis Brade (Phyllanthaceae) after 50 years, as well as its occurrence in Minas Gerais State in southeastern Brazil. We provide a taxonomic diagnosis, in situ photographs, a distribution map, and a reassessment of its conservation status, which will contribute to our knowledge of this rare and endemic species as well as our ability to protect it.

Family Phyllanthaceae is one of the largest segregates of the eudicot order Malpighiales and its species are herb, shrub, and tree, which are mostly distributed in tropical regions. Certain taxonomic discrepancies exist at genus and family level. Here, we report chloroplast genomes of three Phyllanthaceae species—Phyllanthus emblica, Flueggea virosa, and Leptopus cordifolius— and compare them with six others previously reported Phyllanthaceae chloroplast genomes. The species of Phyllanthaceae displayed quadripartite structure, comprising inverted repeat regions (IRa and IRb) that separate large single copy (LSC) and small single copy (SSC) regions. The length of complete chloroplast genome ranged from 154,707 bp to 161,093 bp; LSC from 83,627 bp to 89,932 bp; IRs from 23,921 bp to 27,128 bp; and SSC from 17,424 bp to 19,441 bp. Chloroplast genomes contained 111 to 112 unique genes, including 77 to 78 protein-coding, 30 transfer RNA (tRNA), and 4 ribosomal RNA (rRNA) that showed similarities in arrangement. The number of protein-coding genes varied due to deletion/pseudogenization of rps16 genes in Baccaurea ramiflora and Leptopus cordifolius. High variability was seen in number of oligonucleotide repeats while analysis of guanine-cytosine (GC) content, codon usage, amino acid frequency, simple sequence repeats analysis, synonymous and non-synonymous substitutions, and transition and transversion substitutions showed similarities in all Phyllanthaceae species. We detected a higher number of transition substitutions in the coding sequences than non-coding sequences. Moreover, the high number of transition substitutions was determined among the distantly related species in comparison to closely related species. Phylogenetic analysis shows the polyphyletic nature of the genus Phyllanthus which requires further verification. We also determined suitable polymorphic coding genes, including rpl22, ycf1, matK, ndhF, and rps15 which may be helpful for the reconstruction of the high-resolution phylogenetic tree of the family Phyllanthaceae using a large number of species in the future. Overall, the current study provides insight into chloroplast genome evolution in Phyllanthaceae.
